' ENGINE CYLINDER LUBRIGATOR y 'Filed June 2s.. 192e Patented Nov. 19, 1929 vUNITED STATES PATENT OFFICE ARTHUR S. HAWKS, OF ST. LOUIS, MISSOURI, ASSIGNOR TO BUSCI-LSULZER BROS.-

DIESEL ENGINE COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI ENGINE-CYLINDER LUBRICATOR Application filed June 25, 1926. Serial No. 118,460.

This invention relates to engine lubrica-y ,5 der showing two of the improved lubricating devices applied thereto.

Fig. 2 is a horizontal section on an enlarged scale showing the manner of assembling the lubricating device where it extends through ...j the water jacket casing and Fig. 3 is a vertical section, partly broken away for convenience and on a larger scale, on the line III-III of Fig. 1.

The device consists of a plug-like member 3 which can be readily introduced through the jacket wall 5 into connection with a socket and oil duct iii the cylinder proper or liner 3. rlhe body 1 is tubular, having a threaded engagement at its inner end with a socket 2 :ai which is formed in the cylinder wall 8 and at its other end passing through a relatively large hole iii the acket wall 5 and through a gland l secured to the latter. The gland serves also as a cover for the hole in the ggf, jacket wall and the gland packing affords A11i dinally without undue strain. Within the iody 1 there is loosely mounted a filler member G on the inner end oi which, within the socket 2, is secured an end plug 7. This end nlug is telescoped within the end oi the tubu- 15 lar body 1 and, as shown, fits loosely Within the socket 2, the tip of the plug being tapered or otherwise formed so that it does not tit tightly against the socket end. The plug is held against relative rotation on the end ot the body by a pin 13 fixed in the latter and engaging the former. i

The filler member 6 is provided with a slot 8, which, in effect, forms a continuation of the annular oil passage between the filler member and the bore of the body 1. In the end of the plug 7, there is provided an oblique hole 9, which terminates adjacent the oil duct 10, Which latter extends from the upper part of the chamber 2 to the inner surface of the cylinderor liner.A

The outer end of the body 1 is provided with a closure 11 and between the closure and the filler member 6, and to hold the end plug in contact with the chamber end wall, there is preferably provided a spring 12. Lubricant is supplied fronfthe teed line 111 through the branch vpipes 15 which enter the underside of the body 1 adjacent its outer j end.

By screwing the body into the liner so thatv the connection to the pipe 15 is downward, the oil hole 9 will be pointed upwards directly toward the oil duct 10 and thek slot in the filler rod will be on the upper side of the latter close to the entrance to the hole 9 therej by tending to eliminate the possibility oi any air traps in the device. It will be apparent that in the attainment of this result, the cross section of the oil path through the device is kept small, due to the presence of the filler rod, but is yet easily cleansed by the removal of t-he latter.

It will be understood that the arrangement and construction ofthe parts herein described and illustrated are merely exemplary aii'd that the invention is subject to modification Without departing from the scope of the following claims.

I claim- 1. A lubricating device for engine cylinders comprising in combination with the cylinder wall and the cylinder jacket, a lubricating plug body extending therebetween and communicating at its lowest point at one end with the lubricant supply and at the other end secured within a socket formed in said wall and a duct connecting the upper part of said socket with the working surface ot the cylinder wall.

2. A lubricating device tor engine cylinders comprising in combination with the cylinder wall and the cylinder jacket, a tubular body extending therebetween, a filler member within the body and providing an oil space therein communicating at one end with the lubricant supply and at the other end with a socket Jformed in the wall and a duct connecting the upper part oit said socket with the working surface of the cylinder wall.

3. A lubricating device for engine cylinders comprising in combination with the cylinder wall and the cylinder jacket, a tubular body extending therebetween, a iiller member within the body providing an oil space therein communicating at one end with the lubricant supply and at the other end with a socket formed in the wall, an end plug secured to said ller member and loosely fitting Within said socket and a duct connecting the upper part ot said socket with the work ing surface ot the cylinder wall.

l. A lubricating` device for engine cylinders comprising in combination with the cylinder wall and the cylinder jacket, a tubular body extending therebetween, a filler member within the body and providing an oilspace therein communicating at one end with the lubricant supply and at the other end with a socketI formed in the wall, an end plug secured to said Iiiller member and loosely litting within said socket, a passageway extending through said end plug and forming a continuation of said oil space, and a duct conuecting the upper part of said socket with the working surface of the cylinder' wall.

5. A lubricating device for engine cylinders comprising in combination with the cylinder wall and the cylinder jacket, a tubular body extending therebetween, a iiller member within the body and providing an oil space therein communicating at one end with the lubricant supply and at the other end with a socket formedV in the wall, an end plug secured to said filler member and loosely iitting within said socket, a passageway in said end plug forming a continuation of said oil space and terminating in an outlet opening obliquely into said socket and a duct connecting the upper part ci said socket with the working surface ot the cylinder wall.

6. A lubricating device for .engine cylinders comprising in combination with the cylinder wall and the cylinder jacket'7 a tubular body extending therebetween, a filler member within the plug and providing an oil ARTHUR S. HAWKS.
